DevicePlugin 阶段二 Task 3 已完成!✅
**完成内容**
1. ✅ 重构 ScreenPlugin 为 thin wrapper
- 删除 wake_lock_child 和 cursor_hidden 字段
- start_wake_lock/stop_wake_lock 改为发送 DeviceCommand::SetSleepInhibit
- set_cursor_hidden 改为发送 DeviceCommand::SetCursorVisible
- 移除所有平台特定条件编译(#[cfg(target_os = "linux")]
2. ✅ 更新依赖关系
- dependencies() 从 vec![] 改为 vec!["device"]
- Platform 从 Platform::Linux 改为 Platform::Any
3. ✅ 更新测试
- src/core/tests.rs: screen_plugin_must_have_no_dependencies → screen_plugin_must_depend_on_device
**验收结果**
- ✅ cargo check --workspace --all-targets: 零 warning
- ✅ cargo test --workspace: 73/73 测试通过
- ✅ 代码行数从 176 行减少到约 60 行(减少 66%
**架构改进**
- ScreenPlugin 现在只做消息转发,不再直接管理子进程
- 硬件操作统一由 DevicePlugin 管理
- 平台适配逻辑集中在 DevicePluginScreenPlugin 保持平台无关
Task 3 完成,等待 Task 4集成测试开始。

- ScreenPlugin 重构为 thin wrapper
- 删除 wake_lock_child 和 cursor_hidden 字段,不再直接管理子进程
- start_wake_lock/stop_wake_lock 改为发送 DeviceCommand::SetSleepInhibit 消息
- set_cursor_hidden 改为发送 DeviceCommand::SetCursorVisible 消息
- 通过 ctx.tx.send(Envelope) 向 DevicePlugin 发送命令
- 保持 handle_message 对 ScreenLockRequest/CursorVisibility 的接口不变
- 移除所有 #[cfg(target_os = "linux")] 条件编译(平台适配交给 DevicePlugin
- dependencies() 从 vec![] 改为 vec!["device".to_string()]
- Platform 从 Platform::Linux 改为 Platform::Any跨平台能力由 DevicePlugin 提供)
- 代码行数从 176 行减少到 ~60 行(减少约 66%
- 测试更新src/core/tests.rs 中 screen_plugin_must_have_no_dependencies 改为 screen_plugin_must_depend_on_device
- 架构优势ScreenPlugin 现在只做消息转发,硬件操作统一由 DevicePlugin 管理
